5 Minute Snack: Is a package installed? The Package Manager icons tell you!
I noticed this rather recently. It might have been the case for a long time, but I never noticed it before. The Project Manager uses different icons to show if a package is installed or not!
Look at this example:
The very first package icon is colored with a purple box, the last two icons feature a gray box. That is basically the difference between packages being installed or not. The first package for FMX is installed, the package for VCL and the FNC design-time package are not installed.
Sometimes I am surprised about the subtle improvements I still notice in the Delphi IDE after using it all these years.
